Marshall Street delivers transformative programs for teachers, leaders, and schools.

What We Do

At Marshall Street, we believe every student should have the opportunity to live a fulfilled life. These core values guide our work:

  • The true measure of a school can be found in how it serves its most marginalized students.
  • Theory and practice must reinforce each other to dismantle barriers to educational equity.
  • School improvement requires building the capacity of each person in the education system, so we can all be powerful agents of change.
  • Solutions must be created and implemented with schools, adapting for the needs of each community.

Launched by Summit Public Schools, Marshall draws from more than 15 years of institutional knowledge and extensive experience in school improvement. We’ve built an ecosystem of programs that nurture, develop, and retain excellent, diverse teachers and leaders. Through our programs, we increase the capacity of our school partners to carry their work forward in the ways most meaningful to their communities.

Our Approach

To bring our values to life, our community-centered programs focus on K-12 education — students, teachers, school leaders.

Together, our programs work together to put students first and they are rooted in the needs and strengths of the communities we serve. We build our programs to grow and be sustainable, so they continue to achieve impact for as many schools and communities as possible.

These principles underpin our approach:

  • The student experience is paramount to creating equitable schools.
  • Schools must be designed to serve all students, starting with those most marginalized.
  • A strong leader inspires a thriving school community, and supports excellent teachers.
  • Teachers are the linchpin to any lasting change in schools.
  • Students who have teachers and school leaders who reflect their identities experience increased academic and life outcomes.
  • Schools must continuously improve.
